Brief Summary:
This study will investigate whether using oscillating TES (random noise stimulation) or intermittent tDCS will have greater antidepressant effects in depressed subjects, compared to standard tDCS.

Condition or disease Intervention/treatment Phase
Major Depression Device: tDCS (Eldith DC-Stimulator (CE certified)) Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 7 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Study of Transcranial Electrical Stimulation (TES) for the Treatment of Depression
Study Start Date : September 2010
Actual Primary Completion Date : September 2015
Actual Study Completion Date : September 2015

Arm Intervention/treatment
Experimental: Oscillating or intermittent tDCS Device: tDCS (Eldith DC-Stimulator (CE certified))
For participants receiving intermittent tDCS or oscillating TES, one electrode will be placed over the left pF3 electrode site (overlying the left dorsolateral prefrontal cortex and identified on the scalp using an EEG cap based on the 10/20 system) and the other over the right temporal area.

Primary Outcome Measures :
  1. Montgomery Asberg Depression Rating Scale for Depression (MADRS) [ Time Frame: 6 months ]

Ages Eligible for Study:   18 Years to 85 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subject meets criteria for a DSM-IV Major Depressive episode.

Exclusion Criteria:

  • Diagnosis (as defined by DSM-IV) of: any psychotic disorder (lifetime); bipolar disorder; eating disorder (current or within the past year); obsessive compulsive disorder (lifetime); post-traumatic stress disorder (current or within the past year); mental retardation.
  • Subject has not responded adequately to standard tDCS or is not appropriate for trial of standard tDCS (eg depression too chronic in duration)
  • Total MADRS depression score of 20 or more
  • History of drug or alcohol abuse or dependence (as per DSM-IV criteria) within the last 3 months (except nicotine and caffeine).
  • Inadequate response to ECT in the current episode of depression.
  • Subject is on regular benzodiazepine medication which it is not clinically appropriate to discontinue.
  • Subject requires a rapid clinical response due to inanition, psychosis or high suicide risk.
  • Neurological disorder or insult, e.g., recent stroke (CVA), which places subject at risk of seizure or neuronal damage with TES.
  • Subject has metal in the cranium, skull defects, or skin lesions on scalp (cuts, abrasions, rash) at proposed electrode sites.
  • Female subject who is pregnant. However, women of child bearing age are eligible if they have the pregnancy test but will be excluded if they are sexually active and not using reliable contraception (urine test for pregnancy will be used if appropriate).
